I'm cleaning out a long closed Western Ma. luthier shops inventory  and will be selling a lifetime collection of mostly vintage musical instruments and parts. Today I have a  tremolo unit part  from a  Teisco Swinger II  vintage electric guitar. It is pretty crusty, but I oiled it and replaced one screw  it is solid and now works 9 I really don't understand the two springs ) Kawai  bought Teisco in 67 so this pre dates that. 

Please look at all the photos. Please note I am not a vintage guitar expert and I am going mostly from notes left on items. There are NO returns. ASK questions, and LOOK at the photos. Any input is appreciated,  Check out my feedback and my other sales.  Please There are no cracks, all the corners are still there.feel free to ask any and all questions. Shipping will be $10.70 fully insured  in the lower 48 I will combine shipping on items that will fit in one package.
